  • How to Make a Pure Black Photography Background

    I have some rather high power eyeglasses and the plastic lenses make the colors separate on the sides. Especially those LED signs that business are putting outside. I went with glass lenses and the chromatic aberration went away. Thats part of why good camera lenses are glass.

  • How to Make a Pure Black Photography Background!

    I always hated the edge bleed I got when taking a picture with a white background. My DSLR (Kodak SLR/n Pro) would get severe purple fringing if I tried to take a picture of an object outdoors on white fabric or paper.

    Hmm, the images didn't show. I also added a 3rd one. CRT blooming. Basically the pixels are so bright they start to bleed into the surrounding pixels. Notice Scooge's white areas vs the lines to the right. Those stay "in the lines" while the white "colors outside the lines"

    The white would be too bright and cause the nearby pixels that should be dark to be way lightened up. Kind of like if you took the 20 pixels at the edges of the object, went into "levels" and cranked it up. I'm thinking there are too many photons and they are bouncing off the sides of the lens and inside the camera body and hitting areas they shouldn't1st image: purple fringing2d image: chromatic aberration

    I picked up about 18 new 5" touch screen panels that I think were spares for some industrial equipment. I have them listed here if anyone is interested or wants to make me an offer (I only have 6 listed, I got more later, but didn't get time to check them over)http://www.ebay.com/itm/New-SGD-Solomon-Goldentek-LM7810FBL-97-02614-97-02559-5-Touch-Screen-/331894465456

  • How to salvage a DVD Drive For Free Parts

    I work with a scrapyard that dismantles computers & electronics. They have pallet sized boxes of wires, computer cards & motherboards, telecom, old stereo equipment, flat panel displays, DVD drives and pretty much anything else electronicswise. I can buy pretty much anything there, except hard drives, and if anyone wants a bunch of something ( box of 50 DVD drives anyone?), if someone makes it worth my time, I can get it and get it shipped out.
